The majority of infectious diseases currently emerging as human epidemics originated in mammals. Yet we still know very little about the global patterns of mammal-to-human pathogen transmission. As a first step, researchers have assembled summative world maps of what's on record about…

Recent breakthroughs in creating artificial systems that outplay humans in a diverse array of challenging games have their roots in neural networks inspired by information processing in the brain. Scientists are working to explain in depth how humans and other animals learn.

When we exercise, our bones produce a hormone called osteocalcin that increases muscle performance, according to a new study. Osteocalcin naturally declines in humans as we age, beginning in women at age 30 and in men at age 50. This study describes the first bone-derived hormone known to affect…

Although brains -- even adult brains -- are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function. Someday, though, we may actually be able to replace brain cells and restore memory.

A new study found that the NFL, NBA and NHL teams traveling from west to east had a higher winning percentage compared to teams traveling in the opposite direction.

A team of sleep researchers has found that the autonomic nervous system, which is responsible for control of bodily functions not consciously directed (such as breathing, heartbeat, and digestive processes) plays a role in promoting memory consolidation -- the process of converting information from…

A new study found that normal older adults who experience excessive sleepiness during the day or significant fatigue may have more brain atrophy than expected for their age, particularly in areas of the brain that are more susceptible to aging and Alzheimer's disease.

A professor explains how scientists' limited and faulty understanding of the brain hundreds of years ago gave birth to the erroneous idea that amnesia induced by a blow to the head can be cured by a second 'conk.'

An electrical graphene chip capable of detecting mutations in DNA has been developed by engineers. The researchers say the technology could one day be used in various medical applications such as blood-based tests for early cancer screening, monitoring disease biomarkers and real-time detection of…

A new study explains how cancer cells use energy to fuel this switch between motion and proliferation. The researchers identified for the first time a connection between a cancer gene that controls motility and how cancer cells metabolize energy to move and divide so quickly.

New research shows that an over-the-counter sleep aid helps people suffering from occasional sleep difficulties fall asleep in less than 20 minutes, on average, and improves their reported quality of sleep. The first-of-its-kind study characterizes the sleep benefits of diphenhydramine HCI (DPH),…

Studies have demonstrated that oxytocin plays a role in facilitating the perception of emotions in other people's facial expressions. An international study has tested the idea that this phenomenon is related to facial mimicry. The study confirms this facilitating effect, which proves to be more…

Microbiologists have discovered that the Cyanophage N1 virus carries a DNA sequence -- a CRISPR -- that is generally used by bacteria to fight off viral infection. The virus appears to use the stolen bits of immune system DNA to highjack their hosts' immune response.

Citizen journalism is often seen as more democratic form of journalism, where the public contributes to the reporting, analysis and dissemination of news. A sociologist and criminologist has studied the phenomenon and shown some of its downsides, including how it sometimes leads to outright cyber…

A study suggests a new therapeutic approach to treat the development of chronic kidney disease secondary to chronic heart failure, known as cardiorenal syndrome type 2. Researchers suggest inhibiting G protein-coupled receptors (GPCR) could prevent renal damage in cardiorenal syndrome type 2…

Fifteen minutes of daily exercise is associated with a 22 percent lower risk of death and may be a reasonable target for older adults, reveals new research.

Major rainfall across most of Texas triggering hordes of mosquitoes coupled with seemingly constant mosquito-related Zika virus media reports from around the globe may have set the stage perfectly for what one researcher deems as a very significant discovery in our war against Earth's leading human…

Exercise, particularly high-impact activity, builds stronger bones in children, even for those who carry genetic variants that predispose them to bone weakness, according to new research. The scientists say their findings underscore that genetics does not necessarily equate to destiny, and…

Scientists say brewing more flavorsome coffee could be as simple as chilling the beans before grinding. Chilling roasted beans before grinding resulted in narrower distribution of small particles, which during the brewing process allows access to more flavor from the same amount of coffee.

Researchers have unveiled key processes involved in the toxicity of dioxin, an environmental pollutant that has been linked to impaired brain development. In the body, dioxin forms a complex with the protein AhR, which leads to disruption of normal brain development. Further studies on the topic…

The ability to understand and empathize with others' pain is grounded in cognitive neural processes rather than sensory ones, according to the results of a new study.

The so-called artificial pancreas — an automated insulin delivery system for people with type 1 diabetes mellitus — uses an advanced control algorithm to regulate how much insulin a pump should deliver and when. Regulating glucose is challenging because levels respond to a wide-array of variables,…

Scientists have found a way to starve liver cancer cells by blocking a protein that is required for glutamine breakdown -- while leaving normal cells intact. The discovery opens new ways to treat liver cancer.
